CAN OPENER.

Application filed May 15,

My invention relates to can opening devices adapted for the marginalcutting or marginal slitting of can tops.

The essential objects of my invention are adaptability for use upon cansof different dimensions; the insurance of engagement with the canthroughout the slitting operation; the propulsion of the devicecontinuously rather than intermittently; and the at- 1 tainment of theseobjects in an inexpensive and simply operable device.

To the above ends primarily my invention consists in such parts and insuch combinations of arts as fall within the scope of the appen edclaims.

In the accompanying drawings which form a part of this specificationFigures 1, 2, 3 and 4 are a plan, a front elevation, a rear elevationand an end elevation respectively of my opener attached to a can, thelatter being shown fragmentanly, and

Figure 5, a partial section on line 5-5 of Figure 2.

Like reference characters indicate like partsthroughout the views.

As shown my opener consists of a carrier plate 7 provided with adepending bottom portion or lug 9, and having upon one end a verticallydisposed rearwardly directed lateral guide loop 10. Pivoted at one endto the opposite end of the plate 7 by a pivot pin 12 is a flat arm 13projecting through the loop 10 and loose in the latter. Upon the bottomof the arm, at its rear end, isa horizontal bearing lip 15, whileintegral with an intermediate portion of the lower edge is a dependingslightly rearwardly ofi'set knife or blade 17 having an inclined beveled'cutting edge 18 upon its bottom extremity terminating in a beveledpoint 19. A cam lever 21 is pivoted upon a pin 22 in plate 7 above thelatch comprising an arm 23, and cam head 24, engageable with the topedge of the arm 13, and adaptedv to depress or release the latter in theloop 10 by swinging the arm 23 in either direction. In a hole 25- in thelug 9 is journaled a stud or shaft 26 fixed to one end of which is adisk 27 provided with peripheral teeth 28. The periphery of the wheel isslightly beveled, and the teeth are dia onally arranged. Fast to theother end of the shaft is a crank arm 30 with a handle 31. The' disk isin a vertill cal plane parallel with the plane of the blade 17, slightlyspaced from the latter, and

is overlap ed by the same when the arm-13 is at the limit ofits downwardtravel.

In the drawings is shown sufiicient of a cylindrical can to illustratethe operation of my opener. 33 is the side, and 34 the to of the can,and 35 is the usual upwardly an laterally projecting bead upon the canperiphery. In applying the opener to the can the parts are initiallypositioned as shown in broken lines in Figure 3. The rear edge of thelip 15 rests upon the head 35, and the lever arm 23 is then swung in thedirection of the arrow thus moving the arm 13 downwardly, and forcingthe blade 17 1 through the can top 35 into the position shown in fulllines. The blade is now continuously advanced, and an annular slit 37produced, by turning the crank and thus rotating the toothed disk 27whose face slidably engages the can side 33, and whose toothed peripheryen ages the curved under face of the bead 35, thus impelling the late 7and the parts carried thereby aroun the can. In the described operatingposition it will be noted that the overlapping position of the blade 17relatively to the disk 27 serves to lock the device against escape fromthe can. In fact the device cannot be re-- moved from the can after thecompletion of the cutting operation until the lever arm is reversed andthe arm 13 manually elevated to the position shown'in broken lines. Thusinjury to the operator during the cutting operation is prevented. Thebeveled peri hery of the disk and the diagonal disposition of the teeththereof assists in maintaining the opener in snug engagement with thecam during the cutting operation, and furthermore assists in adaptingthe device to use upon cans of different shapes.

I claim 1. A can opener comprisin a carrier plate, 'an arm pivotallyattac ed to the plate, a blade on the arm, a cam lever pivotally mountedon the plate for actuating the arm, an advancing disk rotatablysu portedby the plate parallel with the bl e and adapted to be overlapped therebyand means for rotating the disk.

- 2. A can opener comprising a carrier plate, an arm upon the plate, abearing lip upon the arm, a blade depending from the arm adjacent thelip, an advancing disk rotatably mounted in the plate cooperating git]?the blade, and means for rotating the 3. A can opener com rising acarrier plate, an arm n on the p ate, a lever upon the plate forepressing the arm, a deendlng blade upon the arm, an advancitlgg diskrotatably mounted in the plate spa from the blade and adapted to beoverlapped thereby when the arm is depressed, and: a crank operativelyconnected to the 4. A can opener comprisin a carrier plate, a lateralloop upon the p ate, an arm pivotally attached to the plate and slidablein the loop, a cam lever carried by the plate engageable with the arm, abearing lip on the arm, a dependin offset blade uponthe arm, anadvancing disk rotatably supported b the plate below the arm adjacentthe blade, and means for rotating the disk.

5. A can opener comprising a carrier plate, a horizontally disposed armcarried thereby, a cam lever 11 n the plate above the arm and engageabewith the arm, a horizontal lateral hp upon the lower ed e of the arm, adepending blade u n t e lower edge of the arm, a shaft in t e platebelow the arm, a crank upon the outer end of the shaft, and an advancingdisk comprising a body upon the inner end of the shaft adjacent theblade and parallel therewith provided with a beveled peripheral portion,and diagonally disposed teeth upon the peripheral portion of the disk.

In testimony whereof I have aflixed my signature.
